From the 18 colon scrapings, we obtained 1,365,109 eukaryotic V1-V3 small subunit (SSU)-rDNA high-quality Illumina MiSeq (Illumina, San Diego, CA, USA) reads clustered into operational taxonomic units
Nitrifier and denitrifier molecular operational taxonomic unit
compositions from sites of a freshwater estuary of Chesapeake Bay.
Defining operational taxonomic units
using DNA barcode data.
longissima belong to only one operational taxonomic unit
or to one ecotype or biotype.
The operational taxonomic units
(OTUs) assigned to Monothalamea accounted for up to 50% of the total diversity in some samples, whereas the hard-shelled taxa (Rotaliida, Textulariida, Miliolida) that are familiar to micropaleontologists represented less than 30% of OTUs.
Operational taxonomic units
(OTUs), richness observations (Chao 1), and Shannon-Wiener index (H') were calculated using the DOTUR program .
[p.sub.ij] and [q.sub.ij] are allele frequencies of the jth allele at the ith locus in the two operational taxonomic units
under consideration, [n.sub.i] is the number of alleles at the ith locus, and m refers to the number of loci.
The number of operational taxonomic units
(OTUs) was greater than 1,000 in the original manure, although a similarly high number of OTUs was obtained only for the -20[degrees]C and 4[degrees]C samples during the first week of storage.
PcoA, Principal coordinate analysis; OTUs, operational taxonomic units
A total of 1858 operational taxonomic units
(OTUs) at 97% similarity were assigned to 26 phyla, 245 families, and 705 genera.
Sequences are clustered into phylotypes termed operational taxonomic units
